beam. The inclineot the wood filler oi' the upper carlin (fm-respomls tothe pitch ot the roel of the 'ai'. '.lhe middle oit' the wood liller ofthe upper 'arlin is reressedto refveire the center beam l() 'ot theearroot.

The Z shaped pressed steelV beam ot` the sub-earlin 2 has two fillers l1and 12 clamped thereto, one on each side ot the rertical flange of thebeam. For ,this purpose bolts 13, 13 pass thru each filler an d the eentral flange or web ot' the Z beam to firmly clamp these tillers togetherand to the sides ol the web or flange ot the E beam. The outline o'lIeach of the iillers ll and l2 is the same as that ot the Z steel beamitself and in clamping them in place on the Z beam one o'lf the lillei'shas its bottoni eX- posed and is used for the ceiling nailing stripWhile the other liller has its top exposed and forms the nailing;`sulation supported by the .sub-Carlin. y

In building the car root' according` to my invention the sub-Carlin ishist eian'iped to the inside ot the side plates lll supported on top oteach side oi the ear. Those side plates have the shoulder 15 'formedthereon so that the outer end ol the sub-carlin can rest thereon. Theflanges G and T ot the Z steel beam are placed against the inside ofthel side plate and suitable bolts 1G pass thru .suitable holes providedin these llanges and thru correspoiulinnv holes in the side plate andclamp the ends oi" the sub-carlin rigidlyv in place. against the insideof the side plate to lirn'ily support it thereon. ritter the subcarlinsare anchored in place between the. side plates ol' the car, the ceilingl? coinprising` a series ol matched boards is nailed to the bottom ottheI vfillers or nailing strip 1i), ot' the sub-carlin.

The ship lap 1S is then nailed to the top ol the lillers or insulationnailing strip ll and on top of this ship lap is placed a series otinsulating strips 19, i9. '.lhe upper carlins l are then placed on topol` the insulating strips 19 and anchored in place between the sideplates lll ot the car. For this purpose the horizontal flange 5 ot eachend olf the upper Carlin is nested into a -recess in t ie top ot theside plates while the flanges an d Ll are suitably bolted to the insideot the side plates by means ol the bolts 2li. ',lo the iop ot the woodliller 8 ol the upper carlin are then nailed the root boards 2l, 2lwhich eorer the top ol' the car trom one side plate to the other sideplate. As heretofore described the middle ol' each o ll wood fillers Sol the upper carlins are recessed to receivel the center beam l() et theroot eonnecting lall of the upper earlins with one another.

l From the .foregoing and from an inspection of Figure 5 of the drawingTit will be. seen that by providing an upper and a subcarlin and placingVa series of continuous layers of insulation which may be inade up striptor the inot telt strips or other suitable material between the upperand. Vthe sub-earlins two air spaces are created between the ceiling;`and the root proper ol the ear. Furthermore the insulation is 'formed by(iontii'iuous strips that extend troni one end to the other end of theCar i'orniingj :L continuous and uniform insulating' partition betweenthe two air spaces.

I claim:

1.111 a car rootl construt-tion'.y the eoiubination ot a pair ot sideplates, an upper and a sub-Carlin supported between said side plate withan uniform space between then-i. an insulating partition placed betweensaid upper and said sub-carlins, a ceilingl supported by said subcarlinon the under side thereof and a root supported on said upper Carlin atthe top thereof.

in a car root construction, the eembination oi a pair oi. side plates,an upper and a sub-carli'n .supported between said side plates Ywith anuni'lforni space between them, a series ot continuous layers olfinsulating` material supported on the top ol' said subcarluin. aceilingsupported on the under side of said sid'iafarlin, a rootsupporlial on. he top oll said upper carliu.

3. In a ear root construction. the coinbination o t a pair ot' sideplates`r an upper and a sub-earlin supported between .said side plates`with a unilorni spacing between the-m. a rigid partition supperled ontop olA Said snb-carlin-` a vllexible layer oi insulatingy malerialplaced on top of' said rigid partition, a ceiling` supported on theunder .side ot said sub-Carlin and a. rool supported on top ot saidupper earlin.

al. .ln a car root construction. the combination ol a pair el sideplaies. an upper and a sub-Carlin suppm-ted between said side platesimlependentl.\7 ol each other, an insulatinp` partition separating saidsub-car lin and said upper rai-lin, a Ceiling suspended on 'the underside ot said sub-carliu and a root supported on lop ol' Said uppercarliu, rein'forcingI n'ieinbers atlachcd to s'aid upper and saidsub-carlin-s.

5S. ln a rootA constrimlion, the combination el' a upper arlin and asub-carlin said upperearlin comprising a U shaped pressed steel trame, aliller clamped in place in said Steel i'ranie and projeinoy above thetop thereot'. said sub-earlin comprising Z shaped pressed sleel i'raniehaving` a wood liller elan'iped lo each side thereof and means forsupporting said upper and .siil -eiiilin with a space between them.

7. A roof construction comprising an up" upper carlin from saidsub-carini a yside plate at the ends of said sub-Carlin and upper Carlinand means for supporting said carlins lon said side plates withthe'insulation between thenn i.

8. In a car roof construction for refrigerator cars the combination of apair of side plates supported at each side of the'car, a'

sub-Carlin comprising a Z shaped pressed steel ranie ,supported betweensaid side plates, nailing strips clamped to each side of said Z shapedsteel frame, a ceilino` fastened to one of said nailing strips lbelenrsaid Z shaped steel frame, a ship lap fastened to the other of saidnailing strips above said Z shaped steel frame, an'insulat ing stripplaced above said ship lap, an upper Carlin coniprising'a U shapedpressed steel frame supported between saith side plates above saidinsulating strip,a Wood lilier forming a nailing strip Within said Ushaped steel frame and' projecting above it, roofing boards nailed ontop of said nailing strip projecting froni said upper Carlin. .A
